TERRA-PIT DJ 18 + DJ 18L

HDD Pit Launch Machine

COMPACT, POWERFUL, PRODUCTIVE The TERRA-PIT DJ 18 is the most powerful and productive HDD pit launch machinethat is available

on the world market. Powered by a proven 75 HP HATZ Diesel engine the DJ 18 PIT offers up to 8

tons of thrust and pullback forceand3.000 Nmof torque. With its 95ltr/min of drilling volume and a

maximum drilling pressure of 70 bar you can backream up to 420 mmover lengths of 150

(depending on ground conditions).

AVAILABLE AS A SHORT AND LONG VERSION

The machine is available as a short version (L=2.0 m) and a long version (L=2.5 m). With a width of

only 0.9 mit fits perfectly in anycompact pit.The small footprint and the reduced noise level at the

operator’s ear make the TERRA-PIT DJ 18 user friendly and sustainable. The fast set up time and the

increased movability helps you to operate your machine also in urban area. The machine can be

equipped with an optional rubber crawler.

POSITIONING OF THE MACHINE The 4 hydraulic cylinders position the TERRA‐PIT DJ 18 PIT in the working pit and adjust its inclination during surface launch. They can be adjusted to the frontand rear, sidewise or downwards.

PULLING OF THE PIPE RIGHT INTO THE PIT The break‐apart-system can be moved backwards. Now the backreamer and the new pipe can be pulled into the working pit. All tools can be disassembled in the machine.

HYDRAULIC BREAK-APART-SYSTEM The break‐apart‐system unscrewsdrill rods hydraulically. The clamping force is 11 tons, thebreak‐apart torque is 5.200 Nm.

STOAGE OF THE DRILL RODS At the machine 5 drill rods can be stored.The drill rods are made out of high quality steel. They have a bending radius of 24 m.

CLEAR CONTROL PANEL

All components ofthe TERRA-PIT are clearly arranged. The integrated electrical control of the the

drilling volume takes place by the control panel. For the locating monitor there is a 12 voltage

connection. The launching cradle is equipped with a grounding stake and an electrical strike

alarm.

FLUID ROCK DRILLING The DJ 18 PIT can be equipped with a fluid rock drilling hammer. With this hammer even rock

drilling or drilling in mixed ground conditions is no problem. The control panel has an optional

integrated connection for the air compressor.

HYDRO-CHAIN-DRIVE Thrust and pullback of the driving saddle is done by a hydro-chain-drive. The two static chains are

mounted on the launching cradle.The two engines move along the chain. This is powerful and

sustainable. The hydro-chain-drive operates in both directions with 8 tons. Highest efficiency can

be reached.
